SourceCatalog4FGL

class gammapy.catalog.SourceCatalog4FGL

Bases: SourceCatalog

Fermi-LAT 4FGL source catalog.

• https://arxiv.org/abs/1902.10045 (DR1)

• https://arxiv.org/abs/2005.11208 (DR2)

• https://arxiv.org/abs/2201.11184 (DR3)

• https://arxiv.org/abs/2307.12546 (DR4)

• https://arxiv.org/abs/2602.22148 (FL16Y)

By default we use the file of the DR4 final release (gll_psc_v35.fit.gz) from https://fermi.gsfc.nasa.gov/ssc/data/access/lat/14yr_catalog/

FL16Y break the 4FGL incremental catalog continuity but can be still open with this class (this feature will be deprecated once 5FGL is available).

One source is represented by SourceCatalogObject4FGL.
